As a trusted partner and good Internet citizen supporting strong network security practices, Liaison has been proactively upgrading its customer-facing certificates over the last 18 months to utilize the more secure cryptographic standard for certificates on its strategic platforms. It is now time to begin migrating the Data Xchange Platform (DXP) to the new cryptographic standard. To meet the needs and requirements of our customers, Liaison designed the DXP certificate migration timeline to give all customers and their trading partners sufficient time to prepare for this change while maintaining a stable and secure environment.

What is Changing?
Liaison will begin replacing the current SHA-1 based certificates with the more secure SHA-256 based certificates on its DXP service for both secure inbound and outbound communications such as HTTPS, AS2 and FTPS. Certificate authorities (CA) have stopped issuing SHA-1 based certificates after January 1, 2016 and leading technology vendors such as Microsoft and Google will no longer support SHA-1 based certificates after December 31, 2016 or possibly sooner.

What Do I Need To Do?
NOTE: Users who do not utilize secure protocols to send or receive files on DXP do not need to take any actions to continue using the service.

In order for users to continue accessing the DXP service via secure protocols such as HTTPS, AS2 and FTPS after the certificate change dates above, customers and their trading partners need to confirm their operating systems, middleware and integration applications are capable of accepting SHA-256 based certificates.

Please inform your trading partners of this change by forwarding them this message. In addition, we strongly encourage customers and their trading partners utilize the DXP UAT instance to test and confirm there are no issues with accepting the new SHA-256 based certificates.

The new SHA-256 based certificates for the DXP service can be downloaded from the link below. The new certificates are located in the “New DXP Certificates” section and labeled “DXP UAT Certificates 2016” and “DXP Production Certificates 2016” which will be available starting on March 7th.

If you or your trading partner is not capable of accepting the new SHA-256 based certificates, please contact PlatformMigration@Liaison.com to determine alternative options for accessing the DXP service using secure protocols
